python安装face_recognition错误

1，安装face_recognition ,直接pip install face_recognition 报错。

2，先安装 ：

pip install cmake==3.12.0 -i https://mirrors.ustc.edu.cn/pypi/web/simple

pip install dlib==19.18.0 -i https://mirrors.ustc.edu.cn/pypi/web/simple

报错了，于是去 dlib · PyPI 下载：备注（whl文件只有老版本的才有，新版本只有tar.gz文件。）

执行如下：报错。

pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl
WARNING: Requirement 'dlib-19.8.1-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
ERROR: dlib-19.8.1-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

然后根据百度，查找python支持的包版本，执行

python
import pip._internal
print(pip._internal.pep425tags.get_supported())
报错
File "", line 1, in 
AttributeError: module 'pip._internal' has no attribute 'pep425tags'

于是：直接用pip debug --verbose 命令即可看 pip 支持。

pip debug --verbose

如上图：感觉要么名字包含py36-none-win_amd64,或者py36-none-win_amd64，然后根据路径还是执行了(后面报错了，发现名字是py36,不是cp36.然后看了whl包，没有Py开头的)

pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl -i https://mirrors.ustc.edu.cn/pypi/web/simple
pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl -i https://mirrors.bfsu.edu.cn/pypi/web/simple

但是都报错了：

WARNING: Requirement 'dlib-19.8.1-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
Looking in indexes: https://mirrors.bfsu.edu.cn/pypi/web/simple
ERROR: dlib-19.8.1-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

又从百度上看到了这种：

 于是下载到本地，执行

 C:\Users\Administrator>pip install C:\Users\Administrator\Downloads\dlib-19.8.1-cp36-cp36m-win_amd64.whl

还是报（dlib-19.8.1-cp36-cp36m-win_amd64.whl）错：还是名字不对。

然后一个个试，试出
 

import wheel.pep425tags as w
>>> print(w)

>>> print(w.get_supported())

我感觉 pip install dlib-18.17.100-cp35-none-win_amd64.whl 符合 ('cp35', 'none', 'any')，但是还是报之前红色错误。然后下载到本地看下,也报错。

最后在其它地方，找了dlib-19.17.99-cp37-cp37m-win_amd64.whl，安装成功。

期间，学了下python : 调用百度AipFace做人脸检测_luckyfairy17的博客-CSDN博客_aipface

然后直接下载：pip install face_recognition 下的很慢，还报错

改为：pip install -i https://mirrors.aliyun.com/pypi/simple face_recognition

成功。

发现，要百度，直接加条件，之前写python安装face_recognition，各种报错。

改为：python3.7 安装 face_recognition ，直接查到了

最后安装成功。
